Cranial repair is a routine procedure in neurosurgery and the technique is relatively mature. In cranial repair surgery, the kind of repair material used and the operation level of the surgeon are very important and may directly affect the postoperative repair effect. Some patients ask about the materials used in domestic tertiary hospitals for skull repair. For cranial bone repair surgery, the repair material used by most hospitals in China is still the traditional titanium mesh material, but in fact, this metal material has defects and the repair effect is not very ideal, and there are various postoperative problems occurring in the clinic, such as postoperative infection, rejection, scalp wear, material exposure, affecting CT magnetic resonance examination, sensitivity to external hot and cold environment, poor shaping effect, easy to collapse and deformation by external force, etc. It is easy to collapse and deformation, etc. In fact, there is a new, superior polyetheretherketone PEEK material that can effectively avoid the above-mentioned problems that may arise with titanium mesh materials. PEEK is a special polymer material that is comparable to autologous cranial bone in terms of stiffness, stability, stiffness, strength, elasticity, thermal insulation, histocompatibility, radioactivity, magnetic compatibility, etc. It has good protective properties, comfort, and aesthetics after placement in the human body, making it a new trend in cranial bone repair materials. Of course, the performance of the repair material is one aspect, but the surgeon’s surgical technique is also very important. For example, some hospitals in the industry use polyether ether ketone PEEK for cranial bone repair, and some problems may occur, such as atrophy and sagging of the temporalis muscle, causing the frontal muscles to pile up and bulge out, which is very unattractive. In addition, because the temporalis is a muscle involved in masticatory function, this can also lead to some degree of weakness in chewing when eating. The prevention of temporalis muscle atrophy is a major challenge in skull repair. At present, our team widely uses polyether ether ketone PEEK as cranial repair material, and the team continuously carries out technical improvement and upgrade and material optimization design, unique material thickness and mesh aperture design, material edge fixation groove design, connection piece material upgrade, and adopts unique temporal muscle separation reset suspension fixation technology, which effectively prevents temporal muscle atrophy sagging and maintains tissue activity and functional integrity. Moreover, the team also innovatively introduces the concept of aesthetic plastic surgery, so as to carry out comprehensive PEEK cranioprosthetic plastic surgery, not only to achieve a high degree of recovery of the cranial anatomy, but also to carry out aesthetic plastic treatment of factors affecting the appearance, such as free flaps, subcutaneous freeing, scar treatment, hydrocolloid expansion of scalp defects, etc., finally achieving the overall unity of anatomical integrity, functional perfection and aesthetic appearance.
